Let's assume that the following routing is saved as user settings:
DIGITAL OUTPUT 1 is connected to DIGITAL INPUT 2
DIGITAL OUTPUT 2
is connected to DIGITAL INPUT 1
Autoswitch
enabled
Let's further assume that there is a sync signal on DIGITAL INPUT 1, and no sync signal on
DIGITAL INPUT 2.
Therefore the actual configuration differs from the target configuration (the first output is
automatically switched to the second input).

Result: The status register shows the actual current configuration and the saved user settings.
Command “h”: restore user settings
Description: Via this command the RCM tells the RCS of class m to restore the configuration which is
saved in the user settings. This command has impact on:
the connection of
DIGITAL INPUT 1
the connection of DIGITAL INPUT 2
the status of auto switch
The RCS executes the command and sends the acknowledge which informs via the status
register about status of auto switch, outputs and inputs.
Example. The comamnd
h is sent to the second RCS:
Message
<STX> <TYPE> <ADDRH> <ADDRL> <Body> <STATH> <STATL <CHKH> <CHKL> <ETX>
m0 2 h 37
Assumption:The following configuration represent the user settings: sync signal on
DIGITAL INPUT 1, no sync signal on DIGITAL INPUT 2, and both outputs are connected to
DIGITAL INPUT 1, while auto switch is disabled.

Result: The user settings are restored, previous made modifications of these connections and
functionalities are re-called.
Restoring configurations is an undo command.
